Abstract

A visual prosthesis and methods of allowing a subject to view visual information from an artificial source are provided. The visual prosthesis has one or more electrodes operative to deliver electrical signals to a lateral geniculate nucleus of a mammal, a power supply operative to provide power to the electrodes, a visual information translator operatively connected to the electrode array, and a visual sensor operatively connected to the visual information translator. The visual prosthesis is operative to translate visual information into an electrical signal and transmit the electrical signal to electrodes to stimulate brain activity to recognize visual information.
